I certainly would not disagree with you on this. Even high intelligence has many specializations that are critically needed. But in a very fundamental sense a world with IQs of 70 and 150, with incurable levels of schizophrenia (as an example) and people who are highly goal directed and others who are absolutely not, is one in which inequality and resentment and anger are almost insoluble, at least as far as my imagination can stretch.
